Waste marble powder is a non-reactive material which is generated from sawing, shaping, and polishing convoy operation of marble stone. Nowadays, the waste marble powder is used as a building substance. These materials can be economically utilized to develop some fresh concrete and hardened properties of conventional concrete (CC). Ground granulated blast furnace slag (GGBS) is a pozzolanic material. GGBS contributes to the production of superior cement concrete. In this subject, both marble powder (MP) and GGBS were replaced binder material of CC that is replacement of cement. The replacement of cement is 0, 5%, 10%, 15% for marble powder, and for GGBS 0%, 10%, 20%, 30% respectively. Mix design is targeted for M40 grade concrete. The mix proportion of the concrete is 1:1.36:2.87. The fresh concrete properties of CC are determined by slump test, and for hardened concrete properties, the tests are carried out such as compressive strength, split tensile strength, and flexural strength at 7 days, 28 days, and 90 days of curing under water. The result indicates that conventional concrete replaced by combination of 10% marble powder and 20% GGBS with cement gives the highest compressive strength, and combination of 15% marble powder and 10% GGBS gives the highest split tensile strength and flexural strength. |
